德国多孔隙石质古迹化学增强保护新材料和新施工工艺

Introduction to new Chemicals and techniques for stone preservation

介绍了20世纪90年代德国石质古迹化学增强保护的新材料和新的施工工艺。提出呈皮壳状风化石雕保护的建议。

In the context of preserving natural stone, it is often necessary to consolidate the structure by applying a stone strengthener. Materials based on silicic acid esters have been used for decades throughout the world. In this paper, the chemical mechanism, application limits of stone strengthener based on classic silicic acid ester has been discussed. New developments, so called elastified silicic acid ester has been introduced, developed as a product system to extend what is feasible. The elastified silicic acid ester system is opening new possibility to solve most of damages occurred in stone monuments.
